TDA7491LP

Features
■ 5 W + 5 W continuous output power:
RL = 8 Ω, THD = 10% at VCC = 9 V
■ 5 W + 5 W continuous output power:
RL = 4 Ω, THD = 10% at VCC = 6.6 V
■ Wide range single supply operation (5 V - 14 V)
■ High efficiency (η = 90%)
■ Four selectable, fixed gain settings of
nominally 20 dB, 26 dB, 30 dB and 32 dB
■ Differential inputs minimize common-mode
noise
■ Filterless operation
■ No ‘pop’ at turn-on/off
■ Standby and mute features
■ Short-circuit protection
■ Thermal overload protection
■ Externally synchronizable
